🔮 Falsifiable Predictions (2)
pendingconf 65%
IF we selectively knock down CLOCK in hippocampal CA1 place cells using AAV-shRNA-CLOCK in adult mice, THEN place cell spatial coding accuracy will decrease by ≥35% and the temporal coupling between place cell firing and circadian phase will be disrupted within 4 weeks.
Predicted outcome: ≥35% reduction in spatial information content and ≥40% reduction in circadian-phase locking of place cell firing rates
Falsification: Place cell spatial coding properties remain within normal range (spatial information >1.5 bits/spike, coherence >0.5) and circadian-phase coupling persists despite confirmed CLOCK knockdown

IF we selectively restore BMAL1 expression in the hippocampus of circadian-disrupted BMAL1-flox mice using AAV9-BMAL1 and chemogenetic activation (AAV9-hSyn-DIO-hM3Dq), THEN spatial navigation performance in the Morris water maze will improve by ≥25% (reduced escape latency) within 3 weeks of interv
Predicted outcome: ≥25% reduction in escape latency to hidden platform and ≥30% increase in platform site crossings during probe trial
Falsification: No significant improvement in spatial navigation metrics (escape latency, platform crossings, time in target quadrant) despite confirmed hippocampal BMAL1 expression restoration
